i claims. ,(cl.` arr-182) This invention relates to wrecking tools in general and more especially to manually operated tools for splitting nuts and the like.

Among the objects of the present invention it is aimed to provide Yan improved wrecking tool which can be carried by the user to any desired place in the eld, irrespective of the accessibility of the part of the construction to receive attention.

It is still another object of the present invention to provide a manually operated wrecking tool which can generate excessive cutting power by hand without endangering adjacent parts of the structure receiving attention.

These and other features, capabilities and ad vantages of the present invention will appear from the subjoined detailed description of one speciiic embodiment thereof illustrated in the accompanying drawings, in which Fig. 1 is a side elevation partly broken away in open position.

Fig. 2 is a simil section.

Fig. 3 is a view similar to Fig. 2 showing the gripping arm after it has completed acutting operation. Y l l Fig. 4 is a section on the line 4 4 of Fig.'3.

Fia 5 is en exploded perspective 0f the. carrier and guide.

Fig. 6 is a perspective of the barrel.

In the embodiment illustrated there is provided a claw I having two opposing arms 2 and 3 connected to one another by the intermediate portion 4. The arm 2 in the present instance is provided with a bayonet slot 5 frictionally to receive a gripping tool B consisting of a bar composed of a suitably hardened tool steel substantially triangular in cross section to t the slot 5 with its gripping edge 1 extending therefrom as shown in Fig. 1. Obviously with a friction nt between the bar 6 and the arm 2 it will require a heavy blow to force the bar 6 into the slot 5.

In the arm 3, on the other hand, there is provided an internally screw threaded opening 3, and in the intermediate portion 4 there are provided two tapped internally screw threaded openings 9 and I0 to receive the screws II and I2 passing through the guide I3. The guide I3 is trapezoidal in cross section with its wider base I4 positioned outwardly of the intermediate portion 4 to receive the bayonet slot I5 of the carrier IS.

The carrier I6 is also claw formed having the two arms I1 and I8 which extend from the inar fragmental view partly in termediate portion I9-with'a' circular arcuate opening defined by the arcuate portion 20 of the inner faces of the arms I1 and I8 and vintermediate portion I9 adjacent one another. The inner opposing faces 2I- andA 22 of the arms I1 and i8, respectively, after leaving the arcuate portion 20, approach one another as they extend outwardly from the arcuate portion 20. The arm I1 adjacent its outer freeend is provided with an internallyl screw `threaded 'tapped opening 23 in alinement with the-opening- 24 in the arm i in communication'with the outer, wider opening 25 forming an annular shoulder 23 between the openings 24 and-525 to receive a screw 21, screw threadedly connected in the opening 23 withits head 28 resting onthefshoulder 23; The screw 21 isvprovidedto forman anchor for the cutting too1'29 lwhich has an' opening 30 freely to receive the shank of the screw 21. 1 The cutting tool 29 is preferablyI composed of a suitably hardened toolsteel or the` like having a cutting end 3| and a rounded inner end 32 to fit in the arcuate recess 33 formed in the barrel 34 receding from the cylindricaliace 35l thereof. The barrel 34 has two segmental projectionsA 33 and 31 projecting from its ends inalinement with one another with screw threaded tapped openings 38 and 39, respectively, in the same, disposed substantially concentric to the cylindrical surface 35 of the barrel 34.

The sections 36 and 31 are provided to enter the elongated slots 40 and 4I in the ends of the arms 42 and 43, respectively, secured to the coupling 44 by being welded thereto or otherwise secured thereto. The coupling 44 is in the present instance internally screw threaded to receive the threaded end 45 of the tubular handle 46.

In order to assemble the parts so far described, it is only necessary slidably to mount the carrier I8 on the guide I3, and then secure the guide I3 in place by rst clearing one side of the guide I3 to gain access to one of the screws II or I2 and secure such screw in place, and then sliding the carrier I6 over to the other side to clear the other screw I I or I2, and se-v curing it in place. Thereupon the barrel 34 is placed in the arcuate opening 20, and the cutting tool 29 positioned with its rounded end 32 in the recess 33 and the cutting end 3I extending beyond the free ends of the arms I1 and I8, and then the screw 21 secured in place to extend through the opening 30 in the cutting tool 29. Thereupon without freeing the arms 42 and 43 from the coupling 44, the outer free ends are forced over the projections 36 and 31, relying upon the resiliency in the metal of the arms 42 and 43, and then the screws 41 and 48 secured in the ends of the projections 36 and 31, respectively, with the edges of the heads 49 and 50 of the screws 41 and 48 extending beyond the projections 36 and 31 and engaging the inner faces of the countersunk recesses 5| formed in the arms 42 and 43.

In the threaded 'opening 8 there is screw threadedly connected the threaded end 52 of the tubular arm 53.

In the operation of the device, the work to be 54, is positioned between cut, such as the nut the gripping edge I of edge 3| of the cutting 53 turned to anchor the carrier ting edge 3| of the cutting tool gagement with the nut 54. ing the arm 46 to be in its outermost position, it will only be necessary to swing the arm 46 toward the arm 53 lwhen the cutting edge 3| will be forced into the nut 54 While being rocked from one side to the other. If the iirst actuation is not sufficient to split the nut 54, the arm 46 is again swung into its outermost position, the arm 53 then turned again to clamp the nut 54 securely in position between the cutting edge 3| and the gripping edge 1, and then the arm 45 again actuated, that is, swung toward the arm 53. This operation may be repeated a number of times before the splitting of the nut 54 is completed. It will thus be seen that the present tool presents an effective manuallyoperated tool for successive cutting operations of a device to be cut or split, that the tool need not be excessively heavy, and consequently may be conveniently carried on the person of the wearer, and in turn due to its leverage operation, adjacent parts of the structure receiving attention are not endangered as would be the case by an acetylene torch or by the concussion that accompanies a hammer blow.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
